CF - EWF and clone?

[Guest]

I'm confused about creating an EWF-protected CF image for mass deployment. It seems like EWF and cloning are incompatible

What is the proper procedure for cloning an EWF-protected, bootable CF partition

EWF states that a RAM overlay will be as large as the protected volume (in my case, ~70MB), but El Torito implies it will be mush smaller (32K). My target ETX-P3E has only 128MB RAM; will using a RAM ETF consume most of it

If my application only writes to a separate CF device, just how much with XPe write to the boot partition, and why

Dale,

If you want to clone an image with EWF enabled then there is no easy solution. Don't forget that you may also want to generate new
SIDs on the cloned images and make the changes persistent.
Do you want to disable EWF in your configuration, prepare the image, reseal and close. On cloned images you may first enable EWF and
reboot (easy task with a batch or something like that).
Also, if you use RAM overlay, consider Slobodan's approach that does not require the EWF configuration volume:

The EWF/cloning issues have been discussed many times in this NG:
http://groups.google.com/groups?hl=...a=group=microsoft.public.windowsxp.embedded.*

E.g., you can read solutions from here:

You seem to refer to different things here.
32k is likely EWF configuration volume.
RAM overlay is EWF cache for the changes you make on the protected partition.

My target ETX-P3E has only 128MB RAM; will using a RAM ETF consume most of it?

For the RAM overlay you will unlikely need as much memory as your protected partition size if you properly set up your XPe image.
Read this new great tip about that: http://msdn.microsoft.com/embedded/community/tips/xp/ramewf/default.aspx. Some folks hee
mentioned that their EWF RAM cache was not over 1Mb.

If my application only writes to a separate CF device, just how much with XPe write to the boot partition, and why?

See the tip article.

Thanks, I'll work my way through this!
